Exodus 30:8-10

Modern English Version

⁸ When Aaron lights the lamps at sundown, he must burn incense on it. It is to be a perpetual incense before the Lord throughout your generations. ⁹ You must offer no strange incense on it, nor burnt sacrifice, nor grain offering, and you must not pour out a drink offering on it. ¹⁰ Aaron must make atonement on its horns once a year with the blood of the sin offering of atonement. Once a year he must make atonement on it throughout your generations. It is most holy to the Lord.
